CANTANTE: Optimizing Agentic Systems via Contrastive Credit Attribution
Researchers have developed CANTANTE, a new framework designed to optimize the configuration of large language model-based multi-agent systems. This system addresses the challenge of assigning credit for performance when only system-level scores are available, by decomposing rewards into per-agent update signals. CANTANTE was evaluated on programming, mathematical reasoning, and question-answering tasks, where it demonstrated superior performance compared to existing methods and unoptimized prompts, while also incurring lower inference costs.
